Hi fccanova1973

Then the only other part that can cause this would be the Mainboard.

fix it all as you open.

Problems with Projector Panasonic PT-L501XU after change the lamp


was this bought new or second hand?
There is a "Lamp Time" setting that can be accessd using your remote control, check this setting.
Look on page 40 and after that of your manual about ambient temperature bulb failure.

By powering off or hittign the reset button the bulb should stay on IF the projector is gettign a signal from a device to show an image. If the projector is not hooked up to a device, laptop, TV, etc. the bulb may turn off to save hours of operation.

Hi BEEZELLE

Does the VGA input work ?

If not then the Mainboard is at fault and will need either repair or replacement.

Right , if the indicator light goes from Green to Orange when shutting down , it will be the Powersupply that is giving problems and not the Ballast.

Ok , so the lamp is out then.

Before spending the money on a new Ballast.

Switch on the Projector while the top cover is off and check if all your fans are running.

The red light you see glowing on the Mainboard is quite normal.

Hi there

Have you replaced the lamp ?

If you haven't - take out the lamp and chech for any irregularity on it - i.e. - discolouration , vein like looking marks ( black or white ) and also if the shape of the shaft is off.

If there is no visible damage it might be a faulty Ballast ( lamp's powersupply ) - especially if you cannot get it out of stanby once it has shut down.
